The Cardinal Gray Data Model

Cardinal Gray’s API is built around an opinionated, transaction-agnostic data model that separates what we’re dealing with (the vehicle) from where we’re taking it (the transaction).

Vehicle (descriptive): The source of truth for VIN, make, model, title information, and registration data
Transaction (prescriptive): How you’re working with this vehicle: loan, sale, repo, or salvage

interface AccountData {
  vehicle: Vehicle;    // Required: Always present
  loan?: DirectLoan;   // Optional loan origination data
  repo?: Repo;         // Optional when collateral enters repo status
  sale?: Sale;         // Optional dealer or private ownership transfer
  salvage?: Salvage;   // Optional for salvage/total loss processing
}

The Vehicle Object

Overview

The Vehicle object is the descriptive core of every title entry. It contains:

1. Identity & Classification

{
  vin: "1HGCM82633A123456",        // duh
  year: "2003",                    // Model year
  make: "Honda",                   // Manufacturer
  model: "Accord",                 // Model name
  // enum and state literals of vehicle type, class
  // body, style... and more!
}

2. Ownership Information

vehicle: {
  // vin, make, year, model, motorcycle engine no., etc. 
  title: {
    number: "T1234567",                   // Title number
    issuing_state: "CA",                  // State that issued the title
    issuing_county: "Los Angeles",        // County of issuance (if relevant)
    issuance_date: "01/15/2023",          // When title was issued
    status: "active",                     // Enumeration of title status
    status_raw_text: "ACTIVE - NO HOLDS", // Original DMV portal text

    // Odometer information
    odometer_reading: "45123",
    odometer_code_translation: "ACTUAL",  // ACTUAL | NOT_ACTUAL | EXEMPT

    // Ownership details
    owner_names_one_line: "JOHN AND JANE DOE",
    owners: [{ name: "John Doe", ownership_type: "titled_owner" ... }],
    conjunction: "AND",                   // In the case of multiple owners

    // Lien information
    has_liens: true,
    active_liens: [{
      lien_date: "01/20/2023",
      lienholder: { name: "First Bank", elt_id: "FB123", ... }
    }],

    // Brand history
    brands: [{
      brand: "NONE",                       // Enumerated brand "translation"
      nmvtis_code: "0",
      state_code: "00"
    }]
  }
}

3. Registration Information

Registered vs titled owners are distinguished within the title.owners via the ownership_type enum, which is ordered based on ownership priority!

{
  license_plate: "ABC1234",
  license_plate_type: "PASSENGER",
  registration_status: "ACTIVE",                // ACTIVE | EXPIRED | SUSPENDED/REVOKED
  registration_expiration_date: "12/31/2024",
  registration_issuance_date: "12/31/2023",

  // Registration/title holds
  has_reg_title_holds: false,
  reg_title_holds: [{
    hold_type: "INSURANCE",                    // INSURANCE | LIEN | FEE | SUSPENSION | etc.
    hold_description: "Proof of insurance required",
    issue_date: "06/15/2023",
    source: "DMV"
  }]
}

Data Enrichment: When you POST a title with sync_nmvtis, sync_public, or sync_private flags, Cardinal Gray automatically populates these fields with real-time DMV data. You only need to provide the VIN and we handle the rest.
